Method

How every lot
gets released.

Four stages, no exceptions. A lot that fails at any stage is quarantined and never enters stock.

  1. Intake and quarantine

    Material arrives sealed and is held in quarantine. Nothing is unpacked into stock before a certificate exists.

  2. Independent assay

    A sample goes to a third-party laboratory. Identity by mass spectrometry, purity by HPLC, plus endotoxin and moisture.

  3. Review against specification

    Results are checked against the published limits. Anything outside specification is rejected — not re-tested until it passes.

  4. Release and publication

    The lot enters stock and its certificate goes online, indexed by the lot number printed on the vial.
